Answers
Answer:
Rotations- 1) The movement of the earth on its own axis is called rotation. 2) Rotation causes day and night 3) The earth completes one rotation in 24 hours. Revolution- 1) The movement of the earth around the sun is called revolution.
The imaginary line that separates day from night on earth is called the circle of illumination.
The term "dawn" is synonymous with the start of morning twilight. ... Technically, "dusk" is the period of twilight between complete darkness and sunrise (or sunset).
The day that the Earth's North Pole is tilted closest to the sun is called the summer solstice. ... It is also the day that the Sun reaches its highest point in the sky. The winter solstice, or the shortest day of the year, happens when the Earth's North Pole is tilted farthest from the Sun.
This happens twice a year during Earth's orbit. Near June 21 the north pole is tilted 23.5 degrees toward our Sun and the northern hemisphere experiences summer solstice, the longest day of the northern hemisphere year.
